Arsenal captain Cesc Fabregas knows he is targeted by opposition hatchet men.
Fabregas is often on the end of some robust challenges and believes the Gunners have to stand up to rough treatment from teams looking to knock them off their passing game.
"Everyone thinks 'We are playing Arsenal, we have to go in hard on them', and I have no problem with the contact game," the Arsenal captain said.
"If opponents think that is the best way for them to beat us, no problem, but when you put your foot half a metre high on someone's leg, that is not right.
"It is not the first time this season we have seen challenges like this, but until someone breaks their leg no-one speaks about it.
"It has happened twice to me this season and I was lucky I did not get badly injured.
"I am sure he [Shawcross] did not want to break Aaron's leg, but the tackle was dangerous. It was terrible.
"I am sure he wanted to win the ball, but when your foot is that high only he knows what he was trying to do."
